因springboot框架通常用于前后端分离项目,因此需配置后台允许跨域访问(具体看注释),配置类如下,将该类加入工程中即可。
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.cors.CorsConfiguration; import org.springframework.web.cors.UrlBasedCorsConfigurationSource; import org.springframework.web.filter.CorsFilter; /** * * Create on 2017年7月6日下午8:05:19 * All right reserved */ @Configuration public class CorsConfig { private CorsConfiguration buildConfig() { CorsConfiguration corsConfiguration = new CorsConfiguration(); corsConfiguration.addAllowedOrigin("*"); //允许任何域名 corsConfiguration.addAllowedHeader("*"); //允许任何头 corsConfiguration.addAllowedMethod("*"); //允许任何方法 return corsConfiguration; } @Bean public CorsFilter corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); source.registerCorsConfiguration("/**", buildConfig()); //注册 return new CorsFilter(source); } }
